Abstract
Objectives
To construct a nomogram that predicts the risk of surgery in patients with necrotizing enterocolitis (NEC).
Methods
This retrospective cohort study recruited patients diagnosed with NEC at the Children's Hospital of Soochow University from 2013 to 2023. The neonates were divided into conservative and surgical-treatment groups. Univariate and multivariate logistic regressions were performed to identify factors influencing surgical risk, and a predictive model was constructed.
Results
This study comprised 154 cases of NEC, 103 cases (66.9%) in the conservative group and 51 cases (33.1%) in the surgical group. Multivariate logistic regression analysis revealed that increased bloody stools [odds ratio (OR) 5.066; 95% confidence interval (CI) 1.7396–14.7532; p = 0.0029), oxygen inhalation (OR 1.8278; 95% CI 1.2113–2.7581; p = 0.0041), use of vasoconstrictors (OR 4.4446; 95% CI 1.7157–11.5137; p = 0.0021), portal venous gas (OR 4.5569; 95% CI 1.6324–12.7209; p = 0.0038), and blood sodium (OR 0.8339; 95% CI 0.7477–0.9301; p = 0.0011) were independent factors of surgical risk. The area under the nomogram's receiver operating characteristic (ROC) curve was 0.886. Decision curve analysis (DCA) and calibration curves demonstrated good predictive performance for the nomogram.
Conclusions
The nomogram effectively assessed the risk of surgical intervention in NEC patients, providing new insights and references for diagnosing and treating NEC.
